微胶囊技术在油脂工业中的研究进展

摘要

Microcapsule technology is a common technique in the food industry for preservation and transmission of sensitive substances,such as oils and fats.It overcomes the shortcomings of traditional processes and produces products with good functionality and storage stability.Appropriate microcapsule technology and wall materials were used to encapsulate the target grease and can obtain microencapsulated grease.Compared with the traditional liquid grease,its stability,mobility and biological digestibility increased significantly.It creates some new features of food and has a broad application prospect in food industry.This paper briefly introduces the characteristics of grease,the basic principle of microcapsule technology and its role in the production of oil,and focused on introducing several kinds of wall and core materials which commonly used in microencapsulated grease.The paper summarizes the advantages and disadvantages and the scope of application of commonly methods of oil microencapsulation and its application in food industry.%微胶囊技术是食品工业中用于保存和传递敏感性物质(如油脂)的常用技术,该技术克服了传统工艺的弊端,能生产出具有良好功能性和储存稳定性的产品.选用适宜的微胶囊技术和壁材,将目标油脂封装起来,即可得到微胶囊化油脂.与传统液体油脂相比,其稳定性、流动性及生物消化率显著提高,并产生了一些新的特性,因而在食品领域中具有广阔的应用前景.文中就油脂的特性、微胶囊技术的基本原理及其在油脂生产中的作用进行了简要的概述,并着重介绍了微胶囊化油脂常用的几种壁材及芯材,总结了微胶囊化油脂常用生产方法的优缺点和适用范围及其在食品工业中的应用.
